The 2008 Arizona Official First Day Coin Cover is the 48th in the series. This limited-edition cover - only 35,000 will be produced - features two Arizona quarters from the first day of mintage - May 8, 2008. Each cover includes two quarters, one each from the United States Mints at Philadelphia and Denver, on a handsome display card with one of the four U.S. 42-cent Flags 24/7 stamps. The postmark of June 2, 2008, Grand Canyon, AZ marks the day the Arizona quarters were first released to the Federal Reserve Bank and to the public.
